Study Type: Single-centre retrospective cohort study (2009–2024)

Key Question: Are SOUND/INSEMA findings supporting SLNB omission applicable to cT1N0, HR+/HER2- invasive lobular carcinoma (ILC) with normal preoperative axillary ultrasound?

Key Findings:

• Of 639 patients undergoing upfront surgery with SLNB, 113 (17.7%) had nodal metastases: 3.8% pN1mic, 11.6% pN1, 1.2% pN2, 1.1% pN3. Only 2.3% had extensive (pN2–3) disease.
• This is comparable to node-positivity in the SLNB arms of SOUND (13.7%) and INSEMA (15.1%).
• On multivariate analysis, only lymphovascular invasion (LVI) independently predicted nodal positivity (19% vs 3.2% in node-negative patients, P<0.001). Premenopausal status and high grade were significant on univariate analysis only.

Clinical Relevance: Supports extending SLNB omission discussions to SOUND-eligible ILC, though LVI on final pathology could inform adjuvant decision-making where SLNB is omitted.

Limitations: Retrospective, single-institution design with no outcome data (recurrence or survival), so noninferiority of omission in ILC cannot be directly inferred.

Study Type: Single-centre retrospective analysis of a prospectively maintained database (prognostic model development with internal bootstrap validation)

Key Question: Does the cumulative burden of somatic driver gene mutations (KRAS, TP53, SMAD4, CDKN2A) improve overall survival prediction after curative-intent pancreatectomy for PDAC?

Key Findings:

• Among 663 resected patients (median follow-up 40.8 months), median OS was 28.4 months; 3-year OS was 41.5%.
• Mortality risk rose with each additional mutated driver gene (HR 1.27 per mutation, P < 0.001), independent of clinicopathological factors including CA19-9, nodal stage, neoadjuvant response and adjuvant chemotherapy.
• The integrated model showed moderate discrimination (optimism-corrected C-index 0.676), outperforming AJCC 8th edition pathological staging alone (C-index 0.568; ΔC = 0.122).

Clinical Relevance: Tumour genomics may refine post-resection prognostication beyond AJCC staging, though routine panel sequencing is not standard in NHS pancreatic cancer pathways.

Limitations: Only internal validation was performed, with no external cohort, and discrimination remained moderate; the authors state external validation is required before clinical use.

Study Type: Prospective multicentre observational study (15 Italian centres, n=316)

Key Question: Does intraoperative ICG fluorescence change surgical conduct or nodal staging during minimally invasive D2 gastrectomy for gastric adenocarcinoma?

Key Findings:

• Residual fluorescence after white-light D2 dissection prompted additional dissection in 61/316 patients (19.3%); extra nodes were retrieved in 47/61, of which 10 (21.3%) contained metastases.
• Stage migration occurred in only 3/316 patients (0.9%).
• ICG fluorescence had a high false-positive rate for nodal metastases.

Clinical Relevance: In a Western cohort already achieving a median of 38 nodes, routine ICG adds little staging value and is unlikely to justify its cost or workflow in NHS gastric cancer practice.

Limitations: No comparator arm, and no survival data were reported, so the effect of ICG on oncological outcomes cannot be assessed.

Study Type: Multicentre, open-label, randomised noninferiority trial (19 French hospitals; 208 randomised, 130 in per-protocol analysis).

Key Question: Is ultrasound-guided transvaginal drainage noninferior to laparoscopy for evacuating tubo-ovarian abscess, as measured by 6-week composite cure?

Key Findings:

• Composite cure (no reintervention, no further antibiotics, collection resolved): 72.5% transvaginal vs 77.0% laparoscopy (difference −4.6 percentage points; 95% CI −19.4 to 10.7). Upper-bound confidence limit exceeded the 12.5-point margin, so noninferiority was not established.
• Reintervention was more frequent with transvaginal drainage (13.0% vs 3.3%; P=.046).
• Transvaginal drainage had shorter hospital stay (median 2 vs 3 days) and faster pain resolution. Clavien-Dindo ≥II complications did not differ.

Clinical Relevance: Transvaginal drainage remains a reasonable less invasive option for TOA, but UK clinicians should counsel patients about higher reintervention risk, and this does not support replacing laparoscopy as the reference approach.

Limitations: The primary analysis used only 130 of 208 patients (per-protocol), with a wide confidence interval and an open-label design, limiting the strength of conclusions.

Study Type: Prospective international cohort study with life table (modelling) analysis.

Key Question: What is the residual lifetime risk of ovarian cancer in BRCA1/2 carriers according to current age and timing of risk-reducing BSO?

Key Findings:

• Lifetime ovarian cancer risk with ovaries intact: 55.0% (95% CI 48.8–61.9) for BRCA1 and 24.1% (15.1–36.6) for BRCA2 (4,286 BRCA1 and 1,427 BRCA2 carriers; 249 incident cancers).
• A 30-year-old BRCA1 carrier delaying BSO to age 50 had a projected residual risk of 23.9% (20.7–27.4).
• At age 75 with ovaries intact, residual risk was 8.4% (1.7–22.7) for BRCA1 and 3.7% (0.1–22.7) for BRCA2.

Clinical Relevance: These estimates can support counselling in UK clinics about deferring BSO beyond guideline ages (35 for BRCA1, 45 for BRCA2), and suggest surgery may still merit consideration in older, fit carriers.

Limitations: Short mean follow-up (4.4 years) and wide confidence intervals at older ages make the late-age estimates imprecise.

Study Type: International consensus guideline (WSES) with structured literature reviews, GRADE methodology, and 17 PICO questions.

Key Question: How should adult colon and rectal injuries from blunt and penetrating trauma be diagnosed and managed, including operative strategy and perioperative care?

Key Findings:

• Contrast CT anchors diagnosis, but a negative result does not exclude injury. For suspected rectal injury, adding proctoscopy raises combined sensitivity to ~97%; routine rectal contrast is not recommended.
• Primary repair or resection with anastomosis is preferred over routine diversion in most stable patients. Selective diversion is reserved for persistent vasopressor dependence after damage-control laparotomy, failed fascial closure at first reoperation, or compounded physiological derangement.
• Extraperitoneal rectal injury: proximal diversion by default; no routine presacral drainage or distal washout. Stapled and hand-sewn anastomoses are equivalent; antibiotics ≤24 hours.

Clinical Relevance: Provides a physiology-driven framework to standardise decision-making for UK trauma and emergency general surgery teams, supporting reduced reliance on mandatory stomas.

Limitations: Much of the underlying evidence is observational, and the abstract does not report certainty grades for individual recommendations.

Study Type: Cross-sectional survey (67-item, based on the job demands-resources model) across 10 US medical centres.

Key Question: Which factors are associated with surgical faculty seriously considering leaving, or choosing to stay in, their current post?

Key Findings:

• 41.1% (95% CI 34.3–48.1%) of 209 respondents (46.2% response rate) reported seriously considering leaving. This was higher in first-job faculty (47.2% vs 32.1%, P=.03), those working longer clinical hours (median 50 vs 40, P=.05), and university-academic or university-affiliated settings (45.5%/48%) versus nonprofit independent centres (16.7%, P=.004).
• Leading reasons for considering leaving were dissatisfaction with leadership/governance (60%), poor work-life balance (51.8%), and burnout (51.8%). Age, gender, ethnicity, region and academic rank were not associated.
• Retention was driven by teaching trainees, collegial relationships and case variety.

Clinical Relevance: Leadership quality and workload emerged as the key modifiable drivers of surgical attrition, which is relevant to NHS consultant retention, though the US academic context limits direct transferability.

Limitations: Low response rate with likely non-response bias, and the cross-sectional design captures intent rather than actual departures.
